Fig. 5. Rates of movement and travel distances observed for dynein-containing structures. (a) Velocity histogram of retrograde and anterograde dynein movements. Velocities were measured as an average of distance over time for each run. (b) Histogram of travel distance. Movements with travel distance less than 1 µm were excluded from the analysis. A total of 65 retrograde and 55 anterograde movements were analyzed for (a) and (b).
